Mtengo wotchipa Wotentha/Wozizira Wokulungidwa Q355b/C/D/E/27simn Makonda Osiyanasiyana Utali Wozungulira ASTM Chitoliro Chachitsulo cha Mpweya Chogwiritsidwa Ntchito Pomanga Mitundu Yonse
Kufotokozera Kwachidule:
Mapaipi achitsulo a 27SiMn amagwiritsidwa ntchito kwambiri m'mafakitale amagalimoto, mafuta, mankhwala ndi zotumiza.27SiMn chitoliro chachitsulo chimakhala chokhazikika komanso chokhazikika, ndikukutidwa ndi phosphate mkati ndi kunja.Chitoliro chachitsulo ichi chimagwiritsidwa ntchito makamaka pakuzimitsidwa ndi kupsya mtima popanga zida zopondera zotentha (zigawo zama hydraulic) zomwe zimafuna kulimba kwambiri komanso kukana kuvala, komanso kupondaponda kotentha komwe kumafunikira kulimba kwambiri komanso kukana kuvala.
27SiMn opanda zitsulo chitoliro ali kuuma mkulu, yovuta hardability awiri m'madzi ndi 8 ~ 22mm, machinability wabwino, sing'anga ozizira mapindikidwe plasticity ndi weldability;Kuonjezera apo, kulimba kwa chitoliro chachitsulo sikumachepetsedwa kwambiri panthawi ya chithandizo cha kutentha, koma kumakhala ndi mphamvu zambiri komanso kukana kuvala, makamaka pozimitsa madzi.
Tsopano tili ndi imodzi mwamakina apamwamba kwambiri opangira, mainjiniya odziwa bwino ntchito komanso ogwira ntchito, omwe amawonedwa kuti ndi kasamalidwe kabwino komanso gulu laukadaulo laukadaulo wothandizirana ndisanagulitsidwe / kugulitsa pamtengo wotsika mtengo Hot/Cold Rolled Q355b/C/D/E/27simn Utali Wosiyanasiyana Wozungulira wa ASTM Paipi ya Zitsulo ya Kaboni Yogwiritsidwa Ntchito M'zomanga Zamitundu Yonse, Ndi mfundo zonse za "chikhulupiriro, kasitomala kaye", timalandira ogula kuti azingotiimbira kapena kutumiza imelo kuti tigwirizane.
